Rush sigs are quite well known and have remained fairly consistent for decades. But like any other older band, their sigs have gone through changes.

What do you think of these? This is not a trick question. I am actually trying to figure these ones out and waiting for a reply from NP official authenticator. 

These do have the flavor's of being 1970's signed but I don't have enough examples to make a 100% decision. Any Rush fans out there who might have an opinion?

These are ultra rare if legit
